COMBINATION CHAIR AND CRIB.

Application filed July 29, 1920. Serial No. 399,729.

5 0 (LEE whom it may concern:

Be it known that I, CARL A. CARLsoN, a subject of the King of Sweden, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Combination Chairs and Cribs, of which the following is a specification.

This invention has for its object to provide a convertible article of furniture which shall be capable of use either as a chair or as a crib, and which shall be simple in construction and cheap to manufacture, as well as durable, efficient and practical.

With the above and other objects in view, the invention comprises the construction, arrangement and combination of parts as now to be fully described and hereinafter specifically claimed.

In the accompanying drawing forming a part of this specification,

Figure 1 is a perspective view of the article of furniture as when in use as a chair;

Fig. 2 a side elevation on a reduced scale of the article as when set up for use as a crib; and

Fig. 3 is a detail view of one of the rear legs of the article.

10 denotes a chair seat and 11 denotes rear legs therefor which are preferably integrally secured to the seat as shown. The back of the chair, denoted by 12 is supported from the seat by means of strips 13 of' material which are secured to the back as indicated at 14 and to the seat as indicated at 15. Chair arms 16, secured to strips 13 of material are held in position by means of chair arm supports 17 secured to the chair arms as indicated at 18 and to the seat as indicated at 19. The chair arms extend forwardly beyond their supports, and to the front end of each, as indicated at 20, crib rails 21 are pivotally secured. Short links 22 pivoted to the front of the seat at its opposite edges, as indicated at 23, are pivoted adjacent their lower ends, as indicated at 24, to long links 25 between which extend slats 26. The crib rails, short and long links, and slats, as well as the chair seat and arms and an end member connecting the forward or lower ends of said crib rails and long links to each other, constitute the frame of the crib. The end member, as shown, preferably comprises bars 27 and rods 28 between the bars. The pivotal con nections between the bars and the crib rails and long links can be made in any desirable manger, said connections being indicated at 2 Adjacent its front end on its opposite side edges the chair seat is provided with threaded studs 30 adapted to receive wing nuts 31. The front legs of the chair, denoted by 32, are perforated to receive the threaded studs mentioned, and the wing nuts are adapted to hold the front legs to the seat, as will be obvious. Further, each rear leg is provided near its upper end with a similar threaded stud 30 having a wing nut 31. Braces 33, pivotally secured to the lower portions of the front legs as indicated at 34 are provided with suitable perforations to receive the threaded studs near the upper ends of the rear legs, the wing nuts, as before, holding the braces in position.

At or near their extreme lower ends, as shown in Fig. 1, the short links which are pivoted to the front side edges of the chair seat are each provided with headed studs 35, and the long links pivoted to the short links are provided with notches 36 adapted to be entered by the headed studs. Pivoted to each crib rail as indicated at 37 is a link bar 38 provided with a notch '39 each of which is also adapted to engage the beaded studs. Arms 40 pivoted to the chair back as indicated at 41 may carry a table 42 whereby the chair may serve-as a high chair. Axles 43 and 44 mounted in the lower ends of the front and rear legs. respectively, are for the purpose of rotatably supporting wheels 45 whereby the article of furniture can be easily transported from place to place. As shown very clearly in Fig. 3, the rear legs are provided with arcuate slots 46 which extend approximately longitudinally of said legs, said slots being equipped in their lower ends with offset portions 47. Springs 48, secured to each rear leg as indicated at 49 and to eyes 50 carried by the rear axle normally hold said axle in elevated position so that the rear wheels of the article of furniture do not rest on the floor, but are positioned as shown in Fig. 1. It will be noted in said figure'that the lower ends of the rear legs touch the floor. When it is desired to support the rear legs from the wheels, all that is necessary is to push downwardly on the rear axle and cause it to enter the offset portions of the arcuate slots. To return the rear axle to its elevated position, all that is necessary is to cause said axle to be removed from said offset portion.

links are in alinement Referring to Figs. 1 and 2, it will be seen that each rear leg is additionally provided near its lower end with a threaded stud 30 having a wing nut 31, both for a purpose to be explained.

As hereinbefore mentioned, Fig. 1 discloses the article of furniture as when in use as a chair, a high chair in the present instance. The movable port on of the crib frame, by reason of its weight, is in its lowest position. It will be noticed that the braces which connect the lower portions of the front legs with the upper portions of the rear legs are diagonally disposed in order that the front and rear legs of the chair will be spaced from each other a distance approximately equal to the distance from the front edge to the rear edge of the chair, as is desirable.

When new it is desired to convert the chair of Fig. 1 to the crib of 2, all that is necessary isto lift the end member of the crib frame until the slats between the long with the chair seat. This will cause the headed studs on the short links to engage the notches in the long links, as will be obvious. i Vhen new the link bars are swung downwardly so that their notches engage the headed studs, the movable portion of the crib frame will be dependably supported in horizontal position as will be obvious from an inspection of l? 52. It will be apparent that the article when used a crib can not be properly supported by the front and rear legs positioned as when in so as a chair, for the reason that weight placed on the crib and to the front of the chair seat would cause the article to be tilted over forwardly. Consequently, the crib is caused to be supported in. the following manner. The wing nuts which fasten the front legs and the braces to the chair seat and rear legs, respectively, are u nscrewed and the front legs and braces are removed from their studs. The braces are then pivoted to the studs from which the front legs have been'removed and the front legs are pivoted to the studs carried by the lower portions of the rear legs, the braces of the chair now becoming in effect front legs 51 of the crib and the front leegs of the chair becoming braces 52 between the front and rear legs of the crib, it being understood of course that the front legs and braces of the article of furniture of the invention are of proper lengths with respect to each other and with respect to the rear legs so that the chair and crib will both be disposed in horizontal position when set up as shown and described, and that the frontlegs of the chair are at the same time of sufiicient length to cause the crib to be dependably supported when serving as braces for the crib.

When the article of furniture is in use as a chair, it will be obvious that the space, designated A, may be made to receive the blankets and bed clothing used in connec' tion with the'crib, and that these can be so arranged that a suitable'leg rest for an occupant of the chair is provided.
